Application Default Credentials for use in calling Google APIs.

The Application Default Credentials are being constructed as a function of
the environment where the code is being run.
More details can be found on this page:
https://developers.google.com/accounts/docs/application-default-credentials

Here is an example of how to use the Application Default Credentials for a
service that requires authentication:

&lt;code&gt;
from __future__ import print_function  # unnecessary in python3
from googleapiclient.discovery import build
from oauth2client.client import GoogleCredentials

PROJECT = 'bamboo-machine-422'  # replace this with one of your projects
ZONE = 'us-central1-a'          # replace this with the zone you care about

credentials = GoogleCredentials.get_application_default()
service = build('compute', 'v1', credentials=credentials)

request = service.instances().list(project=PROJECT, zone=ZONE)
response = request.execute()

print(response)
&lt;/code&gt;

A service that does not require authentication does not need credentials
to be passed in:

&lt;code&gt;
from googleapiclient.discovery import build

service = build('discovery', 'v1')

request = service.apis().list()
response = request.execute()

print(response)
&lt;/code&gt;
